Patent DE-2709671-A1 (DE)
Title: Rotating fluidized bed combustor - has sand rotated in horizontal cylindrical drum with steam blown through heated falling sand
Inventor: O'CONNOR CHADWELL
IPC: F23G5/20
Filed: 1977-03-05
Abstract: The heated fluidised bed is formed by rotating a body of sand in a horizontal cylindrical drum, lifting and dropping sand from the bed through the open portion of the drum, and heating the region through which the sand drops. The drum is formed by a cylindrical water wall of pipes connected to a water source and a steam outlet, and annular end plates hold the sand bed and define inlet and outlet openings in the drum. Waste material is simply dumped through the inlet opening and ash is automatically discharged through the outlet opening. The sand is pref. lifted by small cross section, scoop-like baffles so that the coolest sand from the bottom of the bed is heated, and waste particles are not removed from the bed. Auxiliary air can be introduced into the sand bed through a manifold-pipe arrangement.

Title: Storage tank esp. for liquids of low flash point - has double laminated lining with conductive layers earthed
Inventor: WOLF HARALD
IPC: B65D90/46
Filed: 1977-05-03
Abstract: A storage tank for combustible liquids, esp. those having a very low flash point, such as aircraft fuels, has a main load bearing wall of reinforced concrete, and an internal cladding facing the liquid formed by a series of layers of synthetic material resistant to the liquid. The surface layer in contract with the liquid at least, is rendered electrically conductive, incorporation graphite or sinc powder. It can thus be linked to a protective potential such as the earth. Behind this slightly conductive layer, an intermediate layer, for pref. of metal, is profiled so at to form cavities for the detection of leakage, and this good conductor is also connected to earth. System avoids difficulties concerning the hardening of the concrete. Found with other methods of celiminateing electrostatic charging.

Title: Sterilised bottle closed circuit cooling system - with collecting tank and dump valve to prevent contamination
Inventor: DANIEL RUDOLF
IPC: A23L3/36
Filed: 1977-07-01
Abstract: Sterilixed filled containers, e.g. bottles with medicinal fluids, are cooled inside the steriliser by a closed circuit of a sterile liquid (water). A separating appts. includes a collecting tank with a dump valve to extract any accumulated liquid during all operational phases except the cooling phase. This ensures that bottles which have burst during the sterilisation cannot contaminate the sterile coolant. Coolant adhering to the bottles cannot infect the needles used to pierce the elastomer bottle closures.

Title: Printing machine for audio-visual teaching tape - has print image spirally arranged on roller whose tracks are followed by impression unit
Inventor: NUEHRMANN DIETER
IPC: B41F17/00
Filed: 1977-08-23
Abstract: The print image (original) is mounted on the roller of the printing machine in spiral, adjacent tracks on the roller's circumference. The type set lies at right angles to the longitudinal direction of the tracks. The impression unit interacts with the spiral tracks in the axial direction of the roller by means of e.g. a threaded rod which follows the rotation of the roller. The unit senses the spiral track with a mechanism which engages between the individual windings on the roller. Thus e.g. two or more bands can be printed simultaneously.

Title: Shaft furnace cooling plate - includes coolant-contg. pipes with coolant-free ends of pipes mounted in cooling chamber exterior of furnace wall
Inventor: GRICUK LEV D
IPC: F27B1/24
Filed: 1978-02-01
Abstract: A cooler for a shaft furnace comprises a plate having a high heat conducting layer which faces the furnace working space and a low heat conducting layer presented to the furnace wall. Metal pipes are partially filled with coolant and sealed at opposite ends with the longitudinal axis of the pipes being parallel to the interfacial plane of the plate layers. A cooling chamber is arranged exteriorly of the furnace wall and has a coolant circulating therethrough. The upper ends of the pipes are arranged in the cooling chamber and the lower ends of the pipes are rigidly connected to the plate. Used for protection of metallurgical furnaces from heat, esp. shaft furnaces and blast furnace shells. The cooler can remove severe heat fluxes and makes it possible to reduce the weight of coolers adapted for use on metallurgical installations. The design precludes the penetration of water into the furnace working space in case of damage to a pipe.
Patent DE-2805587-A1 (DE)
Title: Electroslag remelting of steel and alloys for turbine rotors - using alkaline earth metal to deoxidise fluorspar contg. slag to obtain very low aluminium content
Inventor: CHOUDHURY ALOK DR ING
IPC: C22B9/18
Filed: 1978-02-10
Abstract: During the melting process the slag, which contains CaF2, is deoxidised by aluminium which is partly or completely replaced by one or more alkaline earth metals. The deoxid. of the slag is pref. undertaken by Ca; or by Mg and/or Ba which may be added as fluorides. Several alkaline earth metals may be used where one is Ca; and the metals are pref. placed in a metal sheath for addn. to the slag. The alkaline earth metals may also form a core in a tubular steel wire driven by a wire feeding machine into the slag. When Al is used for oxidising the slag, the resulting steel contains Ca. 0.02% Al, which is detrimental in some steels, e.g. it can reduce the creep resistance of turbine rotors used in power station plant. The invention reduces the Al content to 0.01% without impairing other properties.

Title: Automatic programs finding on magnetic tape - involves several counted pulses of opposite polarity and separator stage controlled by recording head
Inventor: GOETZKE AXEL
IPC: G06K17/00
Filed: 1978-07-07
Abstract: Clock and code pulses are picked up from the tape and compared with a presettable required value. A stop signal for tape transport is derived from the comparison. Before a program is recorded, a recording key is operated and a certain polarity pulse is recorded. It is followed by a preset number of opposite polarity pulses from a generator, counted by a counter. This is followed by a pulse of the first polarity. A separating stage is used for the search, and the first pulse resets the counter to zero, while the second pulse stops the tape transport.

Title: Pressure disc filter with centrifugal cake removal - having shaft seals protected from the shaft by rotating collar to reduce wear
Inventor: ZILLER JOSEF
IPC: B01D29/00
Filed: 1978-11-07
Abstract: Liq. filter consists of a pressure vessel contg. a series of circular disc elements mounted on a hollow shaft. Slurry is pumped into the vessel, the filtrate passes through the elements and the cake is subsequently removed by rotating the elements to throw it off by centrifugal action. The slurry is sealed from the filtrate run off by a primary seal, held at a distance from the shaft. The shaft is surrounded by a collar which rotates with it and against which the seals are pressed. This reduces seal wear. The collar is clamped onto or held onto the shaft by a frictional coupling and is free to move both radially and axially. For use on disc filters with centrifugal cake discharge. Reduces wear on the shaft seal and thus the maintenance necessary on the filter.
